Introduction

Congratulations on your purchase of this API 500 format compatible
SSL UltraViolet Stereo Equaliser Module. This module has been
specically designed to operate in a 500 format rack such as the
API lunchbox® or equivalent. In common with many such modules,
the nominal input/output level is +4 dBu.

The SSL UltraViolet 500 Series Stereo EQ takes the acclaimed min­imum phase-shift EQ section from Fusion and puts it into the 500
Series format. The UltraViolet EQ takes things a little further than
Fusion by adding two dedicated mid-bands, with a unique Focus
control, for ultimate EQ exibility. An ideal partner to the legendary
500 Series SSL Bus Compressor, the UltraViolet EQ draws on the
SSL legacy of careful selection of frequencies and response curves
to create a musical and intuitive EQ designed to quickly dial in a
radio-ready sound for your mix.

Operation

Please refer to the numbered front panel illustration.

1

IN

The IN button switches the entire module in and out of circuit on
both Left and Right Channels simultaneously. The violet LED to the
left of the name will illuminate when the unit is switched IN.

2

LF and HF Sections

The frequency pots for each band are stepped. The LF band offers
choices of 30Hz, 50Hz, 70Hz or 90Hz. The HF band offers choices
of 8kHz, 12kHz, 16kHz and 20kHz. The gain pots are continuous,
with indents at the 12 o’clock position (0dB) and allow for ±9dB of
gain.

Full mixes tend to benet from a modest amount of 30Hz, 50Hz or
70Hz to add weight, whilst 8kHz and 12kHz are good starting points
for adding tasteful amounts of high-end.

LMF and HMF Sections

4 5

The LMF band has a swept frequency control between 100Hz and

1.1KHz. The HMF band is also a swept frequency control between
400Hz and 6KHz. Each section has a variable ‘Q’ control (see FO­CUS section). The gain pots are continuous, with indents at the 12
o’clock position (0dB) and allow for ±9dB of gain (again see FOCUS
section).

FOCUS™ Switches

Focus mode allows the user to ‘hone in’ on problem frequencies
or specic frequencies they want to accentuate using the LMF and
HMF sections. Pressing the ‘Focus’ switch in, automatically narrows
the chosen Q setting further and increases the range of gain
available beyond the normal +/-9 dB operation. This transforms this
sweet sounding, musical SSL EQ into a more surgical tool.

HPF (High Pass Filter)

The High Pass Filter section is an 18dB/Octave stereo lter with
switched frequency options at 30 Hz, 40 Hz and 50 Hz. The OFF
setting bypasses the lter circuit completely

8

TRIM

The stereo TRIM control provides an output level trim adjustment
with an indent at the 12 o’clock position (0dB) and allows for ±12dB
of stereo gain trim. This is useful to adjust the module output level
to compensate for signicant gain increases in the EQ sections to
avoid overloading devices later in the processing signal chain.
